Start with conditions, not a product
Cutting into a wall or ceiling without proper containment just moves the problem into the rest of the house. Getting the barrier and airflow right comes before any demolition starts.
Build a complete scope
- The wetting source, established before any remediation is costed
- Whether air conditioning against humid air is condensing inside the wall
- How block construction changes what containment and removal involve
- What is removed and what is cleaned, with the reasoning set out
- Verification, plus the humidity control that stops it returning
West Palm Beach context
Containment work here has to account for barrel-tile and flat built-up roofs alike, plus the salt-laden onshore breeze that keeps humidity elevated even between storms. Historic-district homes may also need extra care around original plaster and trim that a newer canal-front build simply doesn't have.
